High Purity Hydrogen Production From Methanol PSA Separation
High Purity Hydrogen Production From Methanol PSA Separation
Sinopec 250Nm3/H Hydrogen Production From Methanol
Technology Application:
Methanol and deionized water are mixed evenly. After vaporization and overheating, under certain conditions of temperature, pressure and catalyst, mixed raw material for reforming reaction to produce reforming gas containing H2, CO and CO2. After pressure swing adsorption(PSA) separation and purification, high purity hydrogen product is prepared.
Diagram of adsorption and separation of gas mixture
As can be seen from the Langmuir isothermal adsorption equation from, at a certain temperature, the desorption is completed by reducing the pressure. Common desorption methods are atmospheric desorption and vacuum desorption, which purpose is to reduce the partial pressure of adsorbate. The adsorption and desorption of as shown in the illustration:
Pressure swing adsorption (PSA) and temperature swing adsorption (TSA) purification process is realized by two properties of adsorbent in the physical adsorption: one is the different adsorption capacity of different components, the two is the adsorption capacity of adsorbate on the adsorbent increases with partial pressure and decrease with increasing adsorption temperature. The first property of the adsorbent, may realize the preferential adsorption of impurity components containing in hydrogen syn-gas for hydrogen purification purposes; for the second property, can achieve adsorbing at high pressure and low temperature, desorbing in low pressure and high temperature. This cycle of adsorption and regeneration achieve the purpose of continuous hydrogen purification. But decrease with increasing adsorption temperature.
